This fact-check does a great job of debunking the myth that cracking your fingers causes arthritis, backing it up with a credible medical source. It also points out other potential risks, like reduced grip strength and tissue irritation. While the source is solid and provides a thorough medical explanation, adding more references and direct quotes could make the argument even stronger. Bringing in multiple perspectives would add depth and further validate the claim. Overall, this is a well researched and well supported fact-check.
